You must consider, when reading this treatise, that mental perception, because connected with matter, is subject to conditions similar to those to which physical perception is subject.
WHEN reading my present treatise, bear in mind that by "faith" we do not understand merely that which is uttered with the lips, but also that which is apprehended by the soul, the conviction that the object [of belief] is exactly as it is apprehended. If, as regards real or supposed truths, you content yourself with giving utterance to them in words, without apprehending them or believing in them, especially if you do not seek real truth, you have a very easy task as, in fact, you will find many ignorant people professing articles of faith without connecting any idea with them.
The great sickness and the grievous evil consist in this: that all the things that man finds written in books, he presumes to think of as true-and all the more so if the books are old.
You know already that most of the lusts and licentiousness of the multitude consist in an appetite for eating, drinking and sexual intercourse.
You will find that there is no other difference of opinion as regards any portions of the Universe, except that the philosophers believe in the Eternity of the Universe and we believe in the Creation. Note this.
For it is said, "You shall strengthen the stranger and the dweller in your midst and live with him," that is to say, strengthen him until he needs no longer fall upon the mercy of the community or be in need.
Know that for the human mind there are certain objects of perception which are within the scope of its nature and capacity; on the other hand, there are, amongst things which actually exist, certain objects which the mind can in no way and by no means grasp: the gates of perception are closed against it.
Further, there are things of which the mind understands one part, but remains ignorant of the other; and when man is able to comprehend certain things, it does not follow that he must be able to comprehend everything.
The business conduct of the disciples of wise men is truthful and faithful.... He does not allow himself to be made a surety or a guarantor and does not accept the power of attorney.... He lends money and is gracious. He shall not take away business from his fellow man.
The key to the understanding and to the full comprehension of all that the Prophets have said is found in the knowledge of the figures, their general ideas, and the meaning of each word they contain.
The more necessary a thing is for living beings, the more easily it is found and the cheaper it is; the less necessary it is, the rarer and dearer it is.
Do not imagine that what we have said of the insufficiency of our understanding and of its limited extent is an assertion founded only on the Bible: for philosophers likewise assert the same, and perfectly understand it,- without having regard to any religion or opinion.
You will certainly not doubt the necessity of studying astronomy and physics, if you are desirous of comprehending the relation between the world and Providence as it is in reality, and not according to imagination.
The whole object of the Prophets and the Sages was to declare that a limit is set to human reason where it must halt.
